EYE-PROTECTOR.

Specification of Letters Patent.

Patented Oct. 2, 1917.

Original application filed December 19, 1914, Serial No. 878,178. Divided and this application filed November 9, 1916. Serial No. 130,396.

To all whom it may concern:

Be it known that I, GEORGE H. DAY, a citizen of the United States, residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented 'certain new and useful Improvements in Eye- Protectors, of which the following is a specification.

This invention relates to improvements in eye protectors, and has particular reference to'that form of protector disclosed in my co-pending application for Letters Patent Serial No. 878,178, filed December 19, 1914, of which the present application is a divis1on.

One of the leading objects of the present invention is the provision of improved construction of bridging or lens connecting members for use in goggles, eye protectors or the like, which shall facilitate the ready relative adjustment of the lenses as desired.

'A further object of the present invention is the provision of a mounting of this character which shall embody bridging or connecting members having separate there- "from'but associated therewith a nose bearing invention.

Figure I represents a view in elevation of one embodiment of my improved construcanother modified form with the nose rest.

Fig. VI is a front view of another modification of my construction.

In the drawings, in which similar charactors of reference are employed to denote corresponding parts throughout the several views, the numeral 1 designates the lens retaining frames for the usual lenses 2, said frames being in the form illustrated pro vided with the screen portions 3, and with end pieces 4 for the car engaging temples 5 shown for securing the parts in position on the face, although it will be understood that head bands or other retaining devices may be employed if preferred.

In that form of invention illustrated in Figs. I and II, I have shown as connecting the lens frames 1, the pair of oppositely looped cross members 6 and 7, the member 6 being shown as having its ends connected to the upper portion of the frames 1 and depending in a downwardly extending 100 or U-shaped portion, while the member is connected to the frame at a point lower than thc'membcr 6 and extends upwardly in an arch, the length of both the members 6 and 7 being preferably considerably greater than the maximum desired distance between the pair of frames 1 so that a loop will always thereof provided be present facilitating desired adjustment of the parts.

In this form of the invention, to most comfortably support the mounting on the face, I have shown as attached to one of the members 6 or 7, in the particular form illustrated, in fact attached to the member 7, a post 8, which may be either straight or looped, as preferred, and which is provided on its lower end with the nose bearing rest or crest pad 9, the post 8 as well as the members 6 and 7 being formed from pliable material so that the several parts may be readily bent to adjust the mounting to the face. In the adjustment of the mounting it is ordinarily necessary merely to grasp the lens frames 1 and either draw them apart opening up the loops of the members 6 and 7 or pressing them together to increase said loops in order to increase or decrease the distance between the lenses as desired to give the correct pupillary distance and fit to the mounting. The: length and adjustment of thepost 8 is such as to ordinarily brlng the nose rest pad 9 in proper position to engage the nose ofthe wearer, it being understood however, that this arm maybe bent'as desired to secure the exact correct fit of the post 9 to the nose, while on account of the attachment of the post to the center of'one-o'f the looped members, the post and thusfthe nose rest, will normall be equally separated or spaced. from the two frames lto properly center the mounting on the face,-although of course the nose rest may be deflected from such position if desired by suitable adjustoulari loop in place of a .plain' open loop,

thus giving greater length to said members in: a less conspicuous manner than would be the case were the loop much elongated over the form shown in Fig. I. The bridge is lpreferably'attached by means of the post 8, however, .as just described in connection withFigs. I andII, and the manner of adjustment is substantially the same.

, Figs IV illustrates .another modification of my invention, in which in place of the member 6 having both its endsattachedto the upper portion of the frames land the member 7 having both ends attached' beneath the point of attachment of theends of the member 6, the said membersare formed as Fig. I with the loop's'or" bends therein but are attached diagonally, that is to say, one end of the member 6 isatta'ched to a lens fralme on one side aboveyand tothe lensframe on the opposite side below corresponding ends of the member 7 while if desired in connection 'with this form the bridge rest may be dispensed with,'m aking an extremely simple construction for light 7 weight frames.

In Figs. -V- and VI, I have illustrated a still further modification of my. invention, particularly adapted forminor or less pro- .nounced adjustments than are the forms hitherto described. In Fig. V, Ihave shown the members 6 and'fas formed preferably with forwardly in placeof upwardly and downwardly ,extending loops, while I have also here illustrated a -modi-fied form of nose rest 9 having 'a pairof loops 10 fitting around the bridging or connecting member 7-so that themember 'l may slide through said loop and enable the bridge to remain in central'correct nose engaging position while at the same time allowing of ready "adjustment ofthe bridging member, as de- "sired. I

In FigfVIyI haveshown "a=*siniilar construct ion in which the members. 6 and 7 are but slightly in place of pronouncedly looped, while I have provided the nose bearingportions llsecured directly to the lens frames l in.place o-f on the: adjustable lens frame connecting member.

From the foregoing descrlption taken in connectlon wlth the accompanyingdrawlngs,

. the construction and generalwadvantages of my improvedconnecting member for the lensr-frames'of -goggles, eye protectors, or

the'like, should be-readily apparent. Particular 'attentiom'however, isinvited to the fact that. by :the use {of'my inventionit *is possible to adjust the lenses in awpara-l'lel direction either inwardly or outwardly without disturbing the axis ofthedenses, thus making it possible to mount prescription lenses in my improved frame, "a matter hitherto rendered practically impossible in ordinary types of adj ustable frame, due to the fact that the adjustment in the previously known frames required a. relative twisting of lenses or the; like tendingto disturb the relationship of the axes I *of the.

lenses, and destroying their prescriptive value. 1

I claim:

1. In an eye protectorfthe combination with a pair of lens frames,-of-=an uppier member having its ends connected to the .two frames and having a central ,loop,

formed therein, and a second member havingits ends connected" to the frames below the ends of the first and being similarly provided with a loop whereby -the distance between the frames may be readily adjusted by opening-or closing ;of wthejloop while maintaining the horizontal relationship of the frames.

2. In an "eye protector, the combination withaapair of'l'ens.--fr-ames, -of an upper member having-its ends connected to the two frames i-and'having a central loop formed therein, and5a -second memberhaving its ends connected to theiframes belowthe ends ofthef first and being'similarly provided with a loop whereby the distance between the frames maybe readilyadjustedby Eopening orclosing of the loop while maintaining the horizontal relationship of the frames, and a-nose-engaging member oarriedby one of said looped members.

3. In a deviceof thecharacter described,

"the' combination with apair oflens frames,

of similar upper and lower connecting bars for the frames, each of. said barsbeingprovide d with a central loop, *and a nose engaging member carriedby thexlower ofi-said 13o bars, substantially as and for the-purpose described.

4. The combination with a pair of lens frames, of means for connecting said frames, said means comprising a bar secured to the upper portion of the two frames and formed with a central depending looped portion, a second bar secured to the two frames below the point of attachment of the first and formed with a centrally upwardly extending looped portion, a nose rest, and a pliable post having one end secured to the nose rest and the other end secured to one of the loops for adjustably connecting the rest to the lens connecting member.

5. In a device of the character described,

Copies of this patent may be obtained for five cents each, by addressing the the combination with a pair of lens frames, of an upper and a lower connecting bar for said frames, said upper bar being formed with a central downwardly extending looped portion and said lower bar being formed with a central upwardly extending looped portion, whereby the lenses may be given a parallel adjustment by corresponding opening or closing of the looped portion.

In testimony whereof I afiix my signature in the presence of two witnesses.

GEORGE H. DAY.
